Adding children to store root

[hsjawanda]

Hi,

I have been trying a few things, have been getting unexpected results, and now I am confused.  So here are my questions:

Is there anything special about adding a node (say, a folder) directly as a child of a store root? I have a store with protocol "workspace" – will the following code work for adding a folder directly under the store root:

// this.storeRef points to the store I am interested in.NodeRef rootNode = nodeService.getRootNode(this.storeRef);// Creating a folder as a direct child of storeRefChildAssociationRef childAssocRef = nodeService.createNode(rootNode,        ContentModel.PROP_CONTAINS, QName.createQName(                NamespaceService.CONTENT_MODEL_1_0_URI, folderName),        ContentModel.TYPE_FOLDER);‍‍‍‍‍‍‍‍‍‍

Does it matter whether I use ContentModel.PROP_CONTAINS or some other QName as the assocTypeQName when adding a child to a store's root?

What are the differences between creating child associations and creating plain-jane associations (NodeService#createAssociation())? I think one of the differences is that (recursive) searching under a parent node will search those nodes related through child associations, but not those related through plain associations – is this correct?

If I don't put any "PATH:" term in my Lucene search, does the whole store get searched? For example, if I construct a query like this:

String query = "+TYPE:\"" + ContentModel.TYPE_FOLDER.toString() + "\"";‍‍‍

will I get back a list of all the folders in the store being searched?  Will the assocTypeQName I use while adding children make a difference to the results of the above query?

I apologize for asking so many questions in a single post, but I am getting confused by some of the results I am seeing :-).

Thanks.

Yes you are quite correct - that should be the searchService.

Thanks for spotting that, we'll change it.

Sure:-)

I got into troubles again with a page navigation… I would like to add an action in browse.jsp in order to access the list of people and create a user thus I want to have in the list of action "manage users" and when I click on it I open users.jsp. So I was adding this code as follow in browse.jsp but when I click the page does not open and stay on browse.jsp:

<rermissionEvaluator value="#{NavigationBean.currentNode}" allow="Write" id="ef_eval1">
     <a:actionLink value="#{Fmsg.manage_users}" image="/images/icons/users.gif" action="manageUsers" styleClass="title" actionListener="#{NewUserWizard.setupUsers}" />
</rermissionEvaluator>

What is wrong here? And what is the currentNode here?

Thanks in advance

[kevinr]

If you want your view (browse.jsp) to be able to navigate to the users.jsp page then you need to add a navigation handler element to the faces-config-navigation.xml file. This is basic JSF knowledge, you should walk through a few basic JSF tutorials on the web to understand how this works.

To add it, edit the faces-config-navigation.xml file, find this section:

   <navigation-rule>      <from-view-id>/jsp/browse/browse.jsp</from-view-id>‍‍‍‍

and add this new navigation case:

      <navigation-case>         <from-outcome>manageUsers</from-outcome>         <to-view-id>/jsp/users/users.jsp</to-view-id>      </navigation-case>‍‍‍‍‍‍

The currentNode object is the current space the user is viewing.

This allows the browse.jsp page to navigate to the users.jsp page.

Thanks a lot..actually I was just finding my error :?

[soeursourire]

I have some problems of configurations:
- I developped a sub-class of UsersBean in the web-client but in this class I need to get storeRef. So when I define my bean in the faces-config.xml I wanted to add this:
<managed-property>
           <property-name>storeUrl</property-name>
          <value>${spaces.store}</value>
      </managed-property>   
But this spaces.store is defined in repository side in repository.properties. So should I add a bean in faces-config to call repository.properties or use directly Workspace\\store…?

[soeursourire]

Why while doing this in my subclass of UsersBean I have credential problems??

NodeRef rootNodeRef = this.nodeService.getRootNode(Repository.getStoreRef());

[soeursourire]

Please help…I am blocked with this problem of permissions….
I do not understand why I cannot do this code in my class added to the WebClient:

NodeRef rootNodeRef = nodeService.getRootNode(Repository.getStoreRef());

although I added variable nodeService to my class with setNodeService and I added my class bean in faces-config.xml. I also tried to give permission to the connected user to access the nodeService as follow:
this.permissionService.setPermission(nodeService.getRootNode(Repository.getStoreRef()), connectedUsername, this.permissionService.getAllPermission(), true);

Are operations on nodeService only possible from Repository? I guess not seeing that we have this.nodeService.getRootNode(Repository.getStoreRef()) from the class NewUserWizard. How should I choose where to create my classes (under Repository or WebClient)?

Should we use transaction only from the Repository and thus from classes under the Repository project? I am using 3differents transactions in my function finish() of MyNewUserWizard: one for storing properties in my node function, one in my node link and another one for my node person, is it not good? If I create a class in Repository can I call it from my jsp page?

When should I use or not transaction?

Thanks for help

[derek]

You can use the transactions wherever you need them.  You shouldn't decide whether or not put a transaction around some code - if it performs multiple operations as part of a business process, then it should get a transaction.  They will just propogate.  Usually, you would have a single transaction for everything in the finish() method.  You can have 3 nested transactions within that, but if you have 3 completely separate transactions, then if the 3rd fails, the others will still have been committed.  That can't be right.  Perhaps you could post your finish() code.

Mmm.  I think you need to post the method here - otherwise it is going to be difficult to know what is going on.

Somehow, giving admin rights on the root to whatever user logs in doesn't seem like a good idea.  But post the code and we'll see.

Thanks a lot for your answer… In my function finish() I was using 3 different transactions because I was getting into troubles while using a single one… Maybe I should do like you said one single transactions including 3others transactions… here is the code of my function finish():
